datatables custom http request

alfaomega83

hi all,
i'm trying to implement server-side processing using a spring controller(like a servlet). my problem is when i try to send extra parameters to the servlet. Everything works fine but i can't use sorting or searching in the generated table.It appears that after the first ajax request the datatables stop calling my servlet when i change search parameters or ordering.....

javarscript code inside jsp :

        $(document).ready(function () {
            $("#prova").dataTable({             
                "bServerSide": true,
                "aLengthMenu": [[ 100 ], [ 100]],
                "iDisplayLength" : 100, 
                //"sAjaxSource": "./ritornaValoriTabella.do?codiDivi=${registroAnticipi.codiDiviAnti}&codiSett=${registroAnticipi.codiSettAnti}&SINSESSIONID=${SINSESSIONID}",                  
                "sAjaxSource":"./ritornaValoriTabella.do",
                "fnServerData":function (sSource, aoData, fnCallback) {
                    aoData.push({"name":"SINSESSIONID", "value":${SINSESSIONID} } ,
                    {"name":"codiDivi", "value":${registroAnticipi.codiDiviAnti}}  ,
                    {"name":"codiSett", "value":${registroAnticipi.codiSettAnti}}  );
                    $.getJSON( sSource, aoData, function(json) {
                        fnCallback(json)
                    });
                },

                    "sLoadingRecords": "Caricamento...",
                    "sProcessing":     "Elaborazione...",
                    "sSearch":         "Cerca:",

                    },
                    "oAria": {
                        "sSortAscending":  ": attiva per ordinare la colonna in ordine crescente",
                        "sSortDescending": ": attiva per ordinare la colonna in ordine decrescente"
                    }
                },
                "aoColumnDefs": [ { "bSortable": false,"aTargets": ['nosort']} ],                           
            });
        });

Can you link to a test case showing the problem, as per the forum rules.

I don't immediately see any problem with the above code. It should always send the data address by fnServerData on each request since you have enabled server-side processing.
